Defined in:
lib/redis_counters/unique_values_lists/expirable.rb

Overview

Список уникальных значений, с возможностью expire отдельных элементов.

На основе сортированного множества. redis4you.com/code.php?id=010

На основе механизма оптимистических блокировок. смотри Optimistic locking using check-and-set: redis.io/topics/transactions

Особенности:

* Expire -

Пример:

counter = RedisCounters::UniqueValuesLists::Expirable.new(redis,

:counter_name => :sessions,
:value_keys   => [:session_id],
:expire       => 10.minutes

)

counter << session_id: 1 counter << session_id: 2 counter << session_id: 3, expire: :never

counter.data > [1, 2, 3]

# after 10 minutes

counter.data > [3]

counter.has_value?(session_id: 1) false
